Spent the morning getting all the cable runs sorted and the pressure sensors zero'd. Switched databases so the servo would run on the differential pressure collected at BSC2 in the LVEA. This will address a long standing Integration issue and work permit. Still need to do similar at EndX before these items are fully resolved. The EndY has been running on the differential for several weeks.
Couple issues here at the corner station: 1) As I was doing some final cable coiling etc this afternoon, I lost the controller signal to the South Pump Station. I valved the PS out to stop the back spinning. I'll restart this next Tuesday; I think I can restart it without harm but didn't want to risk it after being off all morning and commissioning now ongoing.
2) Pressure sensor 3 on Pump Station 3 (3rd from South) has an issue so the signal is actually coming from sensor #2. The apparent 25psi differential pressure across the 3u filter is not true.
3) The medm still shows the Differential Pressure coming from the Main Supply Line Sensor, again it is really coming from BSC2.
Again, I'll deal with issue 1) on Tuesday. For issues 2) & 3) I'll rework the medm to correctly reflect reality.
Attached is the current medm.
Okay, adjusted the medm. So the servo pressure appears to be coming from BSC2 which it is. Also annotated the PS3 sensor issue. I've also adjusted the database calc so the red Pressure NOT OK will go green, the next time I restart the process, next Tuesday. Corrected medm attached.
